Night Vision Will the L3 CNVD-T survive the Scar-17?

[azotos]

I’ve asked around on a couple different forums about this, so sorry if you’re getting tired of seeing it, but snipershide seems to have more concentrated knowledge on NV devices than anywhere else I’ve looked, so I figured I’d give it one more shot.

Let me lead by saying that I know the CNVD-T is not CAR-hardened. Augee of TNVC was not the first person to tell me this but he did give me the most detailed explanation about CAR hardening. I know that the CNVD-T isn’t a specific CAR attachment, so I don’t need another lesson on that.

The literature says that these units are proofed to .50 cal. I assume this probably means they’re good to go on an M107 or M2. The LWTS even has a reticle for the M107 programmed in. Despite this I am still very hesitant to use an old out-of-warranty unit on the famed optics killer. Someone told me that their Scar 20 killed pixels on their Trijicon UTX Xii, which is also .50 cal rated. Someone else said their 17 killed their Perst laser. The more I ask about it the more the body count of the Scar grows. To the contrary, someone else told me that him and his friend both use Trijicon Reap-IRs on scar 17s without issue.

I am curious if anyone here has any first-hand experience or knows of someone else using a CNVD-T on a Scar 17/20. I’m quite fond of both my Scar and my CNVD-T and would like for the marriage to work. But I am being very cautious. The unit already has a horizontal line on the display just below the center that appears after being left on for too long and has to be calibrated out.

should I just sell this thing and get an LWTS? Is the LWTS Scar-proof? UNV’s promotional pics show it on a 17.

i would not hazard to guess because if i was wrong to say go for it, i would feel bad if it broke.
if i told you not to try, i would feel bad about you missing out when it was probably ok.

i know people want to blame scars like covid-19, but really, do scopes or lasers never fail or lose pixels unless they are on a scar 17?
if i was going to be forced to answer i would say only if it was under warranty and covered.

I guess its called a Scar for good reason. Cause it will scar yo wallet up real quick if you ain't careful.

Me, I would play it safe.

What is the draw of the SCAR if it's this hard on optics? Not being a dick, just honestly curious what benefit it offers that makes people consider running dope optics on what seems to be the killer of optics.

Light accurate and reliable. Plus it’s MIL SPEC!!!! Lol

I have a scar and some mil spec thermals including some under warranty. I won’t use them on the scar. In hindsight the scar is over rated.

I would get a Pof revolution or Seekins or something to run the thermal on OP

 

[deersniper]

This thread has a bunch of stiff about broken optics including commentary from a mil trainer that has seen a pile fail

Scar 17s eat optics and accessories

What Optics/lasers/etc will hold up to a Scar17? I hear of high end optics getting broken on scars. I read that .mil had lasers and other accessories redesigned so that they could stand up to a 17 A 100% reliable rifle doesn't do you much good if it makes your optics go down.

Ya that revolution seems to check alot of boxes for guys wanting to push 7.62....

POF Rogue has my attention...

Semi 308 under 6lbs sounds like a good way to build a dedicated night rifle

Assuming it runs without issie

 

[deersniper]

Id get a 22 Creedmoor or 6.5 Creedmoor unless you are just shooting close range pigs or something g.

Well if I had something like an SR-25 I wouldn’t hesitate to put the thermal on it, but I don’t have an SR-25. I didn’t buy the scar to put under a thermal, I bought the thermal with the hopes I could use it on my scar, but it’s doing fine on my .17 right now as a groundhog killer. Balancing weight, durability, reliability, and accuracy, the scar is a leader of the pack as far as “battle rifles” are concerned. The fact that it has a strong forward recoil which destroys some optics and electronics is an unfortunate byproduct of its design. FN could probably alleviate this somehow without sacrificing any of the other things that make the Scar great, but to my knowledge they haven’t made any efforts in that area and probably never will.

Fair enough, wasn't trying to be a dick, was just wondering how it came about....what you need to do is spray some flex seal in that bitch where it slams all the way home. whalaaaaa forward recoil buffer.

 

[deersniper]

You use a thermal to shoot ground hogs? Please expound

Nah no offense taken or anything like that, the general consensus on this everywhere I've asked has been the same. Why risk it, why not just use a different rifle, etc. I will probably end up never putting it on the Scar, but if I do, I want to be as informed as possible.

Really not much to it, I have a zero on it set for my Savage 93r17, and I use it as a standalone scope for shooting groundhogs in my uncle's field.

The Rogue got my attention too, and I came close.....but went with the Revolution DI. Little bit lighter than the piston version. So far so good. Weight and build live up to the hype. Just broke it in this past weekend. Shoots Hornady ELD 178s right at MOA....using the Trijicon Hunter 60. Did a lot of trigger pulling with surplus 147 grain FMJ ammo I had lying around. Had one FTF on my 3rd round I think....but no other issues, even with some rapid firing. I was really expecting more issues given feedback from users stating they had to get up to 150 rounds or so to get everything running smooth. Trigger is clunky, probably never notice it while hunting, but was not a fan at the range. Even with the Hunter 60 on top still feels light and maneuverable. Just need to get it out in the field on some hogs in order to truly break it in.

 

[azotos]

As far as weight is concerned, the CNVD-T actually weighs less than my 1.5/6x Elcan by a couple ounces. And in my experience the CNVD-T works best as a standalone optic. The benefits of using it as a clip-on in front of your day optic (familiarity with your day scope's reticle, adjustments, and zero) are made moot by the fact that the CNVD-T isn't going to let you positively identify and aim at anything past 150m. Not mine, anyways.

That's an attractive waistline on the Rogue though, I'll have to consider one of those if I get a different .308 semi auto. I've been interested in the POF rifles after reading this torture test from the San Bernandino Sheriff's Dept, which makes a claim that the rifle was printing 1.12" groups on average after shooting 66,900 rounds, part of which were in full auto. A claim that I find at best to be dubious.

 

[NFAJohn]

Nah no offense taken or anything like that

I see you just skimmed right over my flex seal comment...shame lol

 

[azotos]

Thought it was a groundhog. Oops.

And I’d skip throwing it on the scar if it were me.

first off, let me object.
there is a thread here filled with optics failures, and not very many of them involve a scar.

the scar is not "hard on optics", provided the optics are built to withstand it.
it is hard on cheap to moderately priced optics or scopes that designed to withstand g forces in only one direction.

i find it hilarious to hear some haters say "scars suck because it made the lens on my scope pop out the front." dur dur.
well i am not one to make fun of the poors, but if your objective lens "pops out", then your scope was a piece of shit that is just glued together.
you should have put it on your airsoft. (no offense to anyone that runs airsoft).

if you don't see a mechanical retaining ring threaded into the scope tube to retain the objective lens, don't put in on a scar.

anyway, so what is good about the scar? it is clean running and durable, and reliable.
(unless you run it on full auto suppressed with the gas not on the right setting and you make a video about how stupid you were).
doesn't have to be cleaned all the time, or every few hundred rounds and there is no blowback, even suppressed.
pretty accurate for a fairly light 7.62.

ok, i admit that some people might like them because they think they are tactical AF.

Please don’t post garbage like this. Sample size of 1 and it’s full of bs. In order to be statistically relevant you need a sample of at least 30.

You can also see that they say it had 2 FTE and 1 double feed yet they're shooting what looks like steel cased ammo such as wolf or some other garbage. OMG a reciprocating Charging handle. Its big and bulky, thats their criticisms. That and all the documented malfunctions... or so they say and its heavy. These dudes are just whining.

Or maybe because they're loved and used by thousands of our own SF to great effect.

Do you think a SF Airborne guy with CHOPS on his damn Airframe helemt or a Navy Seal who elected to make an MP5SD part of his kit are using Scars because that's their only option? Nah, they have freedom in gear selection, they wouldn't be using them if something better was available. But yeah, cawwadooty...

anyways, this is straying from the original purpose of this thread and subforum.

You know how I know you didn’t read my thread? The one with RKIs saying Nightforce’s and Acogs were killed. The one talking about .mil having to have optics and electronics redesigned to hold up on the 17

so you are saying they are now designed to withstand it! awesome.

 

[deersniper]

I don’t know what optics meet the current standards.

Regardless they are going to have a higher failure rate on a 17 versus other platforms.

Doesn’t seem worth it to me. Broken equipment sucks. Even if it is under warranty.

that's fair. i don't have a 17 so it isn't a decision i have to make.

 

[brodband8]

I'm gonna go ahead and say probably not. I have a trijicon utcxII and my scar 17 has caused quite a few dead pixels to pop up on it.

How many rounds?
Did you adjust the gas jet?

Asking because I have the same setup and Trijicon won’t give me a straight answer which leads me to believe they know it ain’t a good idea.

 

[theLBC]

there are softer recoil plates, but i don't expect it will help with scopes.

Are you the same person from my thread on fnforum? Someone on fnforum said a Scar killed pixels on their UTC Xii.

within 300. No I don’t gas it down I’m using Fa762sv so no jet down needed per surefire. Gun has over 10k on it suppressed

I re-jet mine to a 1.35 and I think factory is 1.6. It made a different but not sure it’s enough to unfuck the scars mike Tyson ability.
